PEDESTRIAN INFORMATION SYSTEM

摘要

A pedestrian information system that can provide alerts to a distracted pedestrian related to hazards in the pedestrian's path. The system can detect objects, and determine if the objects are hazardous and if the pedestrian is likely to collide with the objects. The system can then determine from the pedestrian's activity whether the pedestrian is aware of identified hazards. If the system determines that the pedestrian is not aware of the identified hazards, then the system can output audio, visual, and/or haptic alerts to the pedestrian.

1. A system for providing warnings of hazards to a user, comprising:
a first sensor that detects at least one of a region and an object in an environment of the user; a second sensor that detects activities of the user, wherein the first and second sensors are wearable by the user; at least one wearable acoustic transducer arranged relative to an ear of the user; and a processor programmed to:
identify a hazard to the user based on at least one of a detected region and a detected object;determine whether a detected activity of the user indicates awareness by the user of the identified hazard; andupon determining that the detected activity does not indicate awareness of the identified hazard, output to the at least one acoustic transducer an audio warning for the identified hazard.
